21 5.7 Ram 1500. This is my 2nd UOA. I ran an initial UOA to determine TBN after a heavy use run. It had about 5k towing on the 7500 mile interval. TBN at 7500 was 2.1 on PP 5-20 running a Mopar filter.
This sample was at around 53,400 and I shorted the OCI 500 miles or so because I was leaving on a 2500 mile towing trip that week. I’ll start doing one every change from here on out to keep an eye on elevated iron (possibly lifter issues).
As of now everything looks awesome. I don’t tow much in the winter so this OCI was mostly City/highway daily commute.
